C# 无法在Asp.Net中检测到按钮单击

我对asp.net和c#非常陌生，到目前为止还没有用这种语言写过任何东西。 因此，我无法检测到按钮点击

这是我的密码：-

有人能指出我的错误吗？ 注意：-我看到了其他问题，但似乎无法找出我做错了什么，所以不要指向其他问题

提前感谢

更换

<input type="button" runat="server" value="Send" id="enquiry_post" 
       onClick="enquiry_post_click" class="btn btn-primary"> 

与

或

这会导致我的页面在单击时刷新，还有其他方法吗？为了避免整个页面刷新，您可以使用

asp:UpdatePanel

或手动编写的ajax调用。我需要用更新面板覆盖标签吗？您必须将其放在周围-类似

<input type="button" runat="server" value="Send" id="enquiry_post" 
       onClick="enquiry_post_click" class="btn btn-primary"> 

<asp:Button runat="server" Text="Send" ID="enquiry_post" 
     OnClick="enquiry_post_click" CssClass="btn btn-primary"/>

<input type="submit" class="btn btn-primary" id="enquiry_post" value="Send"             
       runat="server" onserverclick="enquiry_post_click"/>
